Quantum entanglement is such a neat phenomenon, but secure communication feels like such a boring application. How much extra security would a quantumly protected communication channel provide over just using some really heavy encryption sent in a normal manner?

That said, who knows what kinda fun could be had with the side channels of our own physics system.

That observation of the communication would break the link, versus capture and (attempt to) decrypt?
Encryption that breaks if someone other than the authorized parties observes it. Something which isn't possible with "traditional" encryption.
Sadly even if we achieve quantum communication it will be only be for military and governments as we have already seen how government and law enfrocement all over the world has been against secure communication between people.

That to me seems like the coolest possibility. Encryption that breaks if someone other than the authorized parties observes it. Something which isn't possible with "traditional" encryption.

That seems very exploitable, an enemy could theoretically intercept all your communications, just to prevent you from communicating.

Seems to me you avoid the problem of large bad actors collecting a lot of encrypted data with the goals of decyrypting one day with better hardware. That said, who knows what kinda fun could be had with the side channels of our own physics system.

One-time pads seem like a much easier solution, and they're never breakable given any amount of computation. They require upfront preparation to trade the pad, but seem a lot easier than quantum anything.

Sounds like a denial of service attack though. Just keep trying to read messages and render the channel unusable.
